High performance parts service near Diamond Bar, CA

it is true, they do "care" at the care shop .mark is the most knowledgeable person I know when it relates to anything about any motor vehicle. I first brought in work truck's for the company I worked for, then my personal pickup, my chevy Tahoe was stolen and striped and his crew put it back together again as it was, mark and his wife rose to run a tight ship and really do care about the work and the customer .they really do back the work without question on the warranty. I have only the very best comments to give, you can trust mark without any concerns because he will have already taken care of any issue before it is a problem. Michael F.

My friend's car broke down on Baseline Rd. Nate was one of the gentlemen that helped us. Great help, service, and hospitality. I'd go back there every time! Jay Bowman

Tony is absolutely amazing. He is honest, trustworthy and I felt comfortable leaving my car with him. Though he didn't fix my problem due to my having a warranty he was happy that my car was getting fixed though not by him. Will def be coming back and referring him to friends and family Cristina R.

I've had good luck taking my jeep here for servicing. The mechanics here were able to solve a problem that kept causing the engine light to constantly come on. I'd taken my jeep elsewhere in town and the problem was never resolved until I brought my car here. I would definitely recommend this shop. Staff is courteous, professional, and has kept my 15 year old vehicle running smoothly! I will definitely continue to have all work done on my car here at George's Sierra Shell. Nancy

Excellent service. Prices are way better than taking it to a dealership and these guys know what they are doing. They even solved a break issue that the dealer couldn't figure out. Den G. Newport Beach, CA

Friendly and quick service.

Dealership quality service without the dealership prices. Family owned and operated. I have been bringing my cars here for more than 20 years.

Let me tell you about JCW Auto Repair. On 8/9/2024 I was traveling from Berkeley CA after visiting my son, daughter in law and toddler grandson back to my home in north coastal San Diego. I had my 5 month old Corgi puppy with me, (she was a champ the entire trip). I noticed during the grapevine approaching the LA National Forrest the engine seemed to be working hard. I saw freeway signs recommending drivers turn off their AC during the steep grades and incline and I did so. Google maps redirected me to go through Pasadena to SD vs LA as LA rush hour traffic was slammed on Friday. Travel slowed considerably and I noticed my temperature gauge starting to rise in the stop and go traffic. I turned off the AC again, it was 107 degrees outside. Across the freeway from me was a Subaru car dealership, but it was now 5:01 and I know the service dept would be closed. I took the very next exit as I could see it was an industrial area and there had to be something there. I pulled over in some shade to let the car temp gauge to cool down. I saw the car repair shops were all closed. I thought about calling AAA, but what could they do other than tow me? I called my brother in law in SD, he had me pop the hood and check the coolant which was almost empty. He directed me to drive a few miles just west of my location to an O'Reilly auto parts store and he would coach me how to add the coolant. I started to drive about a block and found JCW Auto repair with the bay doors still open. It was clear everyone was closing up but stayed to help me. Jed immediately went to work, I popped the hood, he could smell the radiator heat. Jed immediately noticed my radiator cap was broken. I explained I had taken my Subaru to the dealership two days prior to my road trip to have the oil changed, tires rotated and the fluids all checked. Jed said the service department should have caught this broken radiator cap. Two jugs of coolant. Jed tried to find a used radiator cap that would work, he finally took one off his own personal vehicle that fit my Subaru. Jed cautioned me to drive the rest of the way to SD at normal speeds with no AC. It was blazing hot out there. He even gave me a jug of water if the temp gauge started to rise again and explained do not open the cap until it cools down. Jed seemed genuinely concerned and worried but felt I should be able to make it to San Diego if I take it easy. I asked Jed how much I owed him and Jed told me to give him whatever I thought was right. I am a widow traveling alone, I am beyond grateful for Jed dropping what he was doing to take care of me and get me on my way. He had along day at work and was ready to go home. Jed really saved me and my little puppy. He saved me an expensive repair bill or even my car breaking down on the freeway. I shudder at the danger of that. My sons and my family are exceptionally grateful too. It should be noted when I got to San Clemente I turned the AC on and the temperature gauge never moved from the middle center line. It was so chilly in the cabin my fingers and feet were numb with cold air. I would definitely, most assuredly take my vehicles to JCW Auto repair for all my service needs and might even drive to Azusa from SD for such quality excellence in service. This is the America I grew up in, where there was honesty, integrity and high moral character among our car mechanic professionals, where a handshake was considered to have as much value associated with it as a man giving his word of honor. JCW is exceptional car service care. Jed and his crew are consummate professionals. Again my profound heartfelt thanks

Very helpful, knowledgeable and accommodating. They should change their name because they do much more than just tuneups and lube jobs. And, as a bonus, they are quick and friendly. One of the employees even offered to give me a ride there and back when my car had to be kept for a few days.

Established in 2000. I Erick Voss started Euro West Rovers back in 2000 then I moved on 2006 to Fullerton, Were I had a small custom shop for 8 years. Manny worked with me at Euro West for the 6 great years that I owned it and continued to work at Euro West after I moved on. One day him and I got to talking about how much fun we had at Euro West and decided we should join forces and work together again. So we looked for a new shop and found this building in April 2015 with 11,000 sq ft. this place will give us the opportunity to do the work and service that we feel is lacking in the service industry with honesty and integrity. Manny and I put our hearts and souls in everything we do for our customers and we are here for the long term! We have an open door policy, so if you are in the neighborhood come by and check us out!

Excellent service! Jonathan helped me get my car rolling strait and even got me lunch. Ill definitely be back Jerry Ryan

This place is a scam and rip me off.... took my car in for not starting. they piggy back a connector to my fuel pump relay and charged me for something that it was not even replaced!!!! found out from another shop when the car have the same issues and symptoms. DON'T TAKE TO THIS PLACE!!! call them and never call me back. DO NOT TAKE TO THIS PLACE!! THEY RIP PEOPLE OFF THE OWNER IS A CROOK!!!

Brought my Honda Accord in for ac repair, the guys at aa fixed it right away and gave me a great price. I have found my auto repair shop!

My sons Mustang was in our garage seems like forever we tried to get it towed to a shop but they wouldnt send a flat bed tow truck even when we request one about 3xs so my husband decided to put the fuel pump in himself while at the Auto Zone my husband met Ali and Ali gave him some advice and his ph# and said that he was mobile.We then decided to have Ali put the pump in. You can tell he KNOWS what he's doing/talking about.Ali had the fuel pump in it didn't take him long at all. And the price was GREAT!! From now on Ali will be our Mechanic and no one else!! THANK YOU ALI!!!
